Family Gerridae

Aquarius paludum paludum (Fabricius)

On the surface of both permanent and temporary water bodies, prefers large reservoirs with open water surface and clear of vegetation, also along the shores of lowland rivers, in irrigation canals, large rice paddies, fields, oxbow lakes and sloughs of rivers, flooded quarries and floodplain lakes; distinct large aggregations in the summer months, with up to several hundred individuals; found on top of the water surface film; zoophage (run over the pond surface film to catch insects from the surface); multivoltine; overwinters as imago. Trans Eurasian-Oriental.

Gerris argentatus Schummel

In standing water with partly overgrown surface; zoophage; bivoltine ( Kiritshenko 1964); overwinters as imago. Trans-Palearctic.

Gerris lacustris (Linnaeus)

In quiet ponds, lakes, and floodplain waterbodies with developed emergent and floating aquatic vegetation on the surface; zoophage (preys on small aquatic arthropods); multivoltine ( Kanyukova 1982); overwinters as imago. Trans Palearctic.

Gerris costae fieberi Stichel

On the surface of various water bodies, widespread in puddles, ponds and in flooded rice paddies; zoophage; probably bivoltine; overwinters as imago. West Eurasian.

Gerris odontogaster (Zetterstedt)

Found in essentially all rivers, freshwater lakes and temporary pools in the country; lives on the surface of standing or slow moving water bodies partly overgrown by emergent vegetation, and in reeds along lake shores, quickly populates puddles formed after rain; neustonic; zoophage (preys on all life stages of mosquitoes); bivoltine; overwinters as imago, migrating to terrestrial sites for diapause ( Vepsäläinen 1971). Trans-Eurasian.

Gerris sahlbergi Distant

On the surface of standing and slow moving floodplain water bodies and in flooded rice paddies; zoophage (preys on Culicidae ); bivoltine ( Kanyukova 2006); overwinters as imago. East Palearctic-Oriental.

Gerris sphagnetorum Gaunitz

In wetlands with standing water, primarily sphagnum bogs ( Kanyukova 1982); zoophage (preys on Culicidae ); bivoltine; overwinters as imago. West Eurasian.

Gerris thoracicus Schummel

Found primarily on the surface of small ponds or small, slow moving flowing water, rarely in shallow, nearshore waters of large lakes or rivers; zoophage; bivoltine; overwinters as imago. West Palearctic.

Gerris lateralis Schummel

Primarily in small, permanent and shaded standing water bodies, including desert springs; zoophage (preys on various insects falling into the water); bivoltine; overwinters as imago. Trans-Eurasian. Limnoporus rufoscutellatus (Latreille)

On the surface of shallow, standing waters partially overgrown by emergent aquatic vegetation, found in shaded areas among the stems of aquatic plants in floodplain water bodies, in overgrown areas of ponds and large lakes, in wetlands, occasionally along river banks; ecologically adaptable and very common, avoids open water areas; zoophage (important predator of midges); bivoltine, with only one generation per year reported from Finland to Austria ( Vepsäläinen 1974, Damgaard and Andersen 1996); overwinters as imago. Trans-Palearctic.

Heterobates dohrandti Bianchi

In fast flowing rivers, forms large aggregations, sometimes "…in an infinite number …moving against the current" ( Kiritshenko 1952); natural history and ecology poorly known. Iranian-Turanian.
